  I am working on an IRIS 120GTX with a Genlock board running 3.2 and have the
following problem.  For some reason when I am using the Genlock with de3 set to
RS 170 changing entries in the colormap table do not work correctly, without
Genlock it works fine.  I copied the code directly out of cg2.c to change the
mode.
  To see an example of what I'm talking about (only if you have a Genlock board
with a TV attached) run /usr/4Dgifts/examples/video/cg2 and while in Genlock
mode run /usr/demos/old/light (light makes heavy use of the colormap.)  Is
there a way to work around this problem without going to rgbmode?
